To all whom t may concern:

Be it `known that I', `Grns'rav Suma, asub ject of the Emperor of Austria-Hungary, residing at Vienna, Empire of .Austria Hungary, have invented certain new and useful Improvements in Hydraulic Compressors; and .I do hereby declare the following to be a full, clear, and exact descrip tion of .the invention, .such as .will enable others skilled in the art .to which it appertains to make and use the same.

This invention relates to hydraulic compresscrs and has for its object to provide a reliable and eiicient hydraulic compressor of simple construction.

In the annexed drawing Figure 1 is a diagrammatic section of a hydraulic compressor embodyingthis invention. Fig. 2 shows a detail' of the same on a larger scale, Fig.

3 shows a modification.`

I and II, Figs. 1 and .are two compressor chambers arranged side'by side.

K is the holder for ,the compressed .air provided with a pipe fw leading to a pressure gage M, a pipe a leading to the consumption devices for the compressed air branching oil' from the pipe wand cocks or valves being suitably arranged lin the ipes w and a as usual. The 4holder K is urther connected by a pipe r to the compressorchambers I and II such pipe being provided with a cock or yvalve s and a non-return 4valve t, non-return valves n a? being interposed between the pipe 1' and the compressor chambers I and II.

Each of the compressorv chambers I and II is provided with anlair injector J" J2 respectively of the usual construction .operated by vvater under pressure, the air admissionpipes of such injectors being provided with non return valveslo and 02.1'espectively. In each of the compressor chambers -a le'ver 16' and b2 respectively is pivot'd at,one of "its ends m and m2 .respectively and carries a` float 1S andS2 lrespectively at ,its 4other end. `Each of these levers is adaptedto opcrate a valve `el and d2 'in a pipec ,and c2 respectively connecting the .air spaceof y.the compressor chambers .I and *II respectively with cylinders j and fzmoun-ted on such compressor chambers. l

The float S2 moves downward jclosing the valve d2 but. a non-return valve I as the compressor chamber I is so far filled `With water that the ioat S in the same is raised, permitting air under pressure -to flow from the chamber I through' pipe c and* valve d into the cylinder f the plunger g' f of t-he latteris raised (the air pressure in the j f anda non-return valve c" connected witlr.

`the Waterisupply pipe F cylinder f2` having been reducedA to the atmospheric pressu're as above described) and' the cocks DD. are so turned as to cut ofi' the water supply fromvt-he injector J and lo shut the u ater discharge pipe F2 .and to open The chamber II is thenagain filled with Water While water is discharged from the chamber I and Athe air under pressure escapes from the cylinder `or arranged in the valve d" into the cham# j L ber I. Thus Water is alternately supplied 4to and discharged from the chambers .l and II which in turn supply air under pressure alternately to the holder K` `so that the ap- `paratas opcratles practically continuously as lon(T as .vater under )ressure is su )lied to the pipe E. The valves or cocks 0 O are preferably so adjusted that the same time is j required forfillingone chamber and for discharging` the Water from the other.

.In .themodification shown in Fig. for

, in float valve chambers v5 'v6 respectively are` the non-return valves 0"(22 float valves n3 livl substitutedwhich are connected with the pipes ,c7 v8 leading from the injectors J J:

respectively to the compressor chambers lr and Il respectively. The opcrationof these ioatfvalves is exactly the same as that of the non-return valveso 02. As the air pressure rises in the compressor chambers the air suction ot the injectorsv through the float valve chambers 'v5 v6 ceases and the water level rises in the injectors and in the fioat valve chambers whereby the tloats'are raised against their seats thus preventing any Water from escaping through the chambers 925 ot. Moreover by-passes fr," 7a2' respectively are arranged to each yot the injec-` tors J J?, such by-pass'es being provided with valves 7c and 7.14 respectively, normally closing the same. ,These valves are acteduponpn -the one hand by the water pressufreiinthe lcorresponding injector and on other hands-by springs 7:5 Zz@ respectively. vYl/hen thenpress-ure of the ail-in the compressor chamber Whichisfbeing `filled Withl Water has risen so farv that thevalve 7c3 lor 1* is forced back against the action of the injector but also through its by-pass i I whereby the filling of the compressor cham-v bers with Wateris accelerated.l In all other .respects thefconstruction and operation of the modification shown in Fig.` 3 is exactly the same as those of the apparatus shownin Fis.1and2. 4
